Long-term biliary complications after liver surgery leading to liver transplantation

Mesenchymal Stromal Cell Therapy in Novel Porcine Model of Diffuse Liver Damage Induced by Repeated Biliary Obstruction

In liver surgery, biliary obstruction can lead to secondary biliary cirrhosis, a life-threatening disease with liver transplantation as the only curative treatment option. Mesenchymal stromal cells (MSC) have been shown to improve liver function in both acute and chronic liver disease models. This study evaluated the effect of allogenic MSC transplantation in a large animal model of repeated biliary obstruction followed by partial hepatectomy. MSC transplantation supported the growth of regenerated liver tissue after 14 days (MSC group, n = 10: from 1087 ± 108 (0 h) to 1243 ± 92 mL (14 days); control group, n = 11: from 1080 ± 95 (0 h) to 1100 ± 105 mL (14 days), p = 0.016), with a lower volume fraction of hepatocytes in regenerated liver tissue compared to resected liver tissue (59.5 ± 10.2% vs. 70.2 ± 5.6%, p < 0.05). Volume fraction of connective tissue, blood vessels and bile vessels in regenerated liver tissue, serum levels of liver enzymes (AST, ALT, ALP and GGT) and liver metabolites (albumin, bilirubin, urea and creatinine), as well as plasma levels of IL-6, IL-8, TNF-α and TGF-β, were not affected by MSC transplantation. In our novel, large animal (pig) model of repeated biliary obstruction followed by partial hepatectomy, MSC transplantation promoted growth of liver tissue without any effect on liver function. This study underscores the importance of translating results between small and large animal models as well as the careful translation of results from animal model into human medicine.

Single-Center Experience of Living Donor Liver Transplantation for Patients With Secondary Biliary Cirrhosis

BACKGROUND

Secondary biliary cirrhosis (SBC) represents a unique form of cirrhosis that develops in the liver secondary to persistent biliary obstruction. This study aimed to review the living donor liver transplants (LDLTs) performed at our center for patients with SBC and end-stage liver disease and to share the perioperative strategies undertaken to achieve satisfactory outcomes.

METHODS

The medical records of 29 patients who underwent LDLT for SBC between December 1994 and July 2018 at the Asan Medical Center (Seoul, South Korea) were retrospectively reviewed. Their clinical data were extracted and statistically analyzed. Survival curves were computed.

RESULTS

The perioperative and in-hospital morbidity rates were 72.4% and 10.3%, respectively. The overall mean recipient follow-up was 80.0 (SD, 66.4) months (range, 0.8-246.8 months). Patient survival rates after 1, 3, 5, and 10 years after transplant were 82.8%, 79.3%, 79.3%, and 79.3%, respectively. For liver grafts, the survival rates were 82.8%, 75.8%, 75.8%, and 75.8% at 1, 3, 5, and 10 years, respectively.

CONCLUSIONS

LDLT is potentially a final lifesaving resort for patients with SBC with portal hypertension. However, considering the difficulty of surgery and perioperative management, LDLT should be performed by experienced transplant surgeons in a center where a multidisciplinary approach is possible.

Liver transplantation as last-resort treatment for patients with bile duct injuries following cholecystectomy: a multicenter analysis

Background

Liver transplantation (LT) has been used as a last resort in patients with end-stage liver disease due to bile duct injuries (BDI) following cholecystectomy. Our study aimed to identify and evaluate factors that cause or contribute to an extended liver disease that requires LT as ultimate solution, after BDI during cholecystectomy.

Methods

Data from 8 high-volume LT centers relating to patients who underwent LT after suffering BDI during cholecystectomy were prospectively collected and retrospectively analyzed.

Results

Thirty-four patients (16 men, 18 women) with a median age of 45 (range 22-69) years were included in this study. Thirty of them (88.2%) underwent LT because of liver failure, most commonly as a result of secondary biliary cirrhosis. The median time interval between BDI and LT was 63 (range 0-336) months. There were 23 cases (67.6%) of postoperative morbidity, 6 cases (17.6%) of post-transplant 30-day mortality, and 10 deaths (29.4%) in total after LT. There was a higher probability that patients with concomitant vascular injury (hazard ratio 10.69, P=0.039) would be referred sooner for LT. Overall survival following LT at 1, 3, 5 and 10 years was 82.4%, 76.5%, 73.5% and 70.6%, respectively.

Conclusion

LT for selected patients with otherwise unmanageable BDI following cholecystectomy yields acceptable long-term outcomes.

Complications of hepatic echinococcosis: multimodality imaging approach

Hydatid disease is a worldwide zoonosis endemic in many countries. Liver echinococcosis accounts for 60-75% of cases and may be responsible for a wide spectrum of complications in about one third of patients. Some of these complications are potentially life-threatening and require prompt diagnosis and urgent intervention. In this article, we present our experience with common and uncommon complications of hepatic hydatid cysts which include rupture, bacterial superinfection, and mass effect-related complications. Specifically, the aim of this review is to provide key imaging features and diagnostic clues to guide the imaging diagnosis using a multimodality imaging approach, including ultrasound (US), computed tomography (CT), magnetic resonance (MR), and endoscopic retrograde cholangiopancreatography (ERCP).

LIVER TRANSPLANTATION FOR BILE DUCT INJURY AFTER CHOLECYSTECTOMY

ABSTRACT BACKGROUND: Bile duct injury is a life-threatening complication that requires proper management to prevent the onset of negative outcomes. Patients may experience repeated episodes of cholangitis, secondary biliary cirrhosis, end-stage liver disease and death. OBJECTIVE: To report a single center experience in iatrogenic secondary liver transplantation after cholecystectomy and review the literature. METHODS: This was a retrospective single center study. Of the 1662 liver transplantation realized, 10 (0.60 %) were secondary to iatrogenic bile ducts injuries due cholecystectomies. Medical records of these patients were reviewed in this study. RESULTS: Nine of 10 patients were women; the median time in waiting list and between cholecystectomy and inclusion in waiting list was of 222 days and of 139.9 months, respectively. Cholecystectomy was performed by open approach in eight (80%) cases and by laparoscopic approach in two (20%) cases. The patients underwent an average of 3.5 surgeries and procedures before liver transplantation. Biliary reconstruction was realized with a Roux-en-Y hepaticojejunostomy in nine (90%) cases. Mean operative time was 447.2 minutes and the median red blood cell transfusion was 3.4 units per patient. Mortality in the first month was of 30%. CONCLUSION: Although the liver transplantation is an extreme treatment for an initially benign disease, it has its well-defined indications in treatment of bile duct injuries after cholecystectomy, either in acute or chronic scenario.

Liver transplantation in the treatment of severe iatrogenic liver injuries

The place of liver transplantation in the treatment of severe iatrogenic liver injuries has not yet been widely discussed in the literature. Bile duct injuries during cholecystectomy represent the leading cause of liver transplantation in this setting, while other indications after abdominal surgery are less common. Urgent liver transplantation for the treatment of severe iatrogenic liver injury may-represent a surgical challenge requiring technically difficult and time consuming procedures. A debate is ongoing on the need for centralization of complex surgery in tertiary referral centers. The early referral of patients with severe iatrogenic liver injuries to a tertiary center with experienced hepato-pancreato-biliary and transplant surgery has emerged as the best treatment of care. Despite widespread interest in the use of liver transplantation as a treatment option for severe iatrogenic injuries, reported experiences indicate few liver transplants are performed. This review analyzes the literature on liver transplantation after hepatic injury and discusses our own experience along with surgical advances and future prospects in this uncommon transplant setting.

Role of Liver Transplantation in Bilio-Vascular Liver Injury After Cholecystectomy

BACKGROUND

The aim of this study was to report 2 cases of liver transplantation (LT) for iatrogenic bile-vascular injury (BVI) sustained during cholecystectomy and to review the literature for LT after cholecystectomy.

METHODS

Between March 2001 and July 2013, within our institution, 12 patients were treated after cholecystectomy, 3 of 12 received LT, 1 for acute de-compensation in a cirrhotic patient and 2 after iatrogenic lesions.

RESULTS

The majority of iatrogenic injury occurred during video-laparocholecystectomy (63,6%; 7/11). Three patients of 12 (25%) received LT: the first patient developed acute de-compensation in chronic and after liver failure. The second patient developed recurrent cholangitis and secondary biliary cirrhosis. The third patient had undergone emergency hepatectomy because of bleeding and subsequent total hepatectomy with porto-caval shunt. Five of 12 (42%) patients were treated with bilio-digestive anastomosis: 1 patient with direct repair on T-tube; 2 patients (17%) with arterial vascular lesion requiring surgical treatment; and 1 patient treated with medical therapy. No deaths occurred. The post-operative morbidity included 1 re-intervention, 3 recurrent cholangitis, 1 anastomotic biliary stricture, 1 anastomotic bile leak, and cholestasis in 3 patients. The overall hospital stays were higher after LT. Median follow-up was 8.25 years (range, 2-14).

CONCLUSIONS

The management of iatrogenic injury during cholecystectomy depends on the time of recognition, extent of injury, experience of the surgeon, and the patient's general condition. If safe repair is possible, BVI should be treated promptly, otherwise all patients should be treated in an experienced center.

Iatrogenic biliary injuries: multidisciplinary management in a major tertiary referral center

Background. Iatrogenic biliary injuries are considered as the most serious complications during cholecystectomy. Better outcomes of such injuries have been shown in cases managed in a specialized center. Objective. To evaluate biliary injuries management in major referral hepatobiliary center. Patients & Methods. Four hundred seventy-two consecutive patients with postcholecystectomy biliary injuries were managed with multidisciplinary team (hepatobiliary surgeon, gastroenterologist, and radiologist) at major Hepatobiliary Center in Egypt over 10-year period using endoscopy in 232 patients, percutaneous techniques in 42 patients, and surgery in 198 patients. Results. Endoscopy was very successful initial treatment of 232 patients (49%) with mild/moderate biliary leakage (68%) and biliary stricture (47%) with increased success by addition of percutaneous (Rendezvous technique) in 18 patients (3.8%). However, surgery was needed in 198 patients (42%) for major duct transection, ligation, major leakage, and massive stricture. Surgery was urgent in 62 patients and elective in 136 patients. Hepaticojejunostomy was done in most of cases with transanastomotic stents. There was one mortality after surgery due to biliary sepsis and postoperative stricture in 3 cases (1.5%) treated with percutaneous dilation and stenting. Conclusion. Management of biliary injuries was much better with multidisciplinary care team with initial minimal invasive technique to major surgery in major complex injury encouraging early referral to highly specialized hepatobiliary center.

Long-term consequences of bile duct injury after cholecystectomy

Late complications arising after bile duct injury (BDI) include biliary strictures, hepatic atrophy, cholangitis and intra-hepatic lithiasis. Later, fibrosis or even secondary biliary cirrhosis and portal hypertension can develop, enhanced by prolonged biliary obstruction associated with recurrent cholangitis. Secondary biliary cirrhosis resulting in associated hepatic failure or digestive tract bleeding due to portal hypertension is a substantial risk factor for morbidity and mortality after bile duct repair. Parameters that determine the management of late complications of BDI include the type of biliary injury, associated vascular injury, hepatic atrophy, the presence of intra-hepatic strictures or lithiasis, repetitive infectious complications, the quality of underlying parenchyma (fibrosis, secondary biliary cirrhosis) and the presence of portal hypertension. Endoscopic drainage is indicated for patients with uncontrolled acute sepsis, patients at high operative risk, patients with cirrhosis who are not eligible for liver transplantation and patients who have previously undergone several attempts at repair. Roux-en-Y hepaticojejunostomy, whether de novo or as an iterative repair, is the technique of reference for post-cholecystectomy BDI. Hepatic resection is indicated in only rare instances, mainly in case of extended hilar stricture, multiple stone retention in one sector of the liver or in patients for whom the repair is deemed technically difficult. Liver transplantation is indicated only in exceptional circumstances, when secondary biliary cirrhosis is associated with liver failure and portal hypertension.

Study of hydatidosis-attributed mortality in endemic area

Background

Cystic hydatid disease is still an important health problem in European Mediterranean areas. In spite of being traditionally considered as a “benign” pathology, cystic echinococcosis is an important cause of morbidity in these areas. Nevertheless, there are few analyses of mortality attributed to human hydatidosis.

Objective

To describe the epidemiology, the mortality rate and the causes of mortality due to E. granulosus infection in an endemic area.

Methodology

A retrospective study followed up over a period of 14 years (1998–2011).

Principal Findings

Of the 567 patients diagnosed with hydatid disease over the period 1998–2011, eleven deaths directly related to hydatid disease complications were recorded. Ten patients (90.9%) died due to infectious complications and the remaining one (9.1%) died due to mechanical complications after a massive hemoptysis. We registered a case fatality rate of 1.94% and a mortality rate of 3.1 per 100.000 inhabitants.

Conclusions

Hydatidosis is still a frequent parasitic disease that causes a considerable mortality. The main causes of mortality in patients with hydatidosis are complications related to the rupture of CE cysts with supurative collangitis. Therefore, an expectant management can be dangerous and it must be only employed in well-selected patients.

Experience using liver transplantation for the treatment of severe bile duct injuries over 20 years in Argentina: results from a National Survey

BACKGROUND

Bile duct injury (BDI) is a severe complication that may arise during the surgical treatment of benign disease and a few patients will develop end-stage liver disease (ESLD) requiring a liver transplant (LT).

OBJECTIVE

Analyse the experience using LT as a definitive treatment of BDI in Argentina.

PATIENTS AND METHODS

A national survey regarding the experience of LT for BDI.

RESULTS

Sixteen out 18 centres reported a total of 19 patients. The percentage of LT for BDI from the total number of LT per period was: 1990-94 = 3.1%, 1995-99 = 1.6%, 2000-04 = 0.7% and 2005-09 = 0.2% (P < 0.001). The mean age was 45.7 ± 10.3 years (range 26-62) and 10 patients were female. The BDI occurred during cholecystectomy in 16 and 7 had vascular injuries. One patient presented with acute liver failure and the others with chronic ESLD. The median time between BDI and LT was 71 months (range 0.2-157). The mean follow-up was 8.3 years (10 months to 16.4 years). Survival at 1, 3, 5 and 10 years was 73%, 68%, 68% and 45%, respectively.

CONCLUSIONS

The use of LT for the treatment of BDI declined over the review period. LT plays a role in selected cases in patients with acute liver failure and ESLD.

Hepatic venous outflow obstruction after hydatid cyst surgery: evaluation with contrast enhanced magnetic resonance angiography

INTRODUCTION

The aim of this study is to present the contrast enhanced magnetic resonance angiography findings of hepatic venous outflow obstruction in patients in whom surgery had been performed for hepatic hydatidosis. No patient history of parasitic hepatic venous invasion or earlier hepatic venous outflow obstruction is present.

MATERIALS AND METHODS

Four men and three women with a history of hydatid cyst surgery underwent contrast enhanced magnetic resonance angiography between April 2001 and June 2006. The mean age was 37.7 years. The mean time duration between the last date of surgery and the date of magnetic resonance angiography imaging was 65.5 months. The site of the hydatid cyst was the right lobe in two patients, the medial segment of the left lobe in two patients, the liver dome in two patients, and the conjunction of the right lobe anterior-left lobe medial segments in one patient. One patient had undergone total and one patient had undergone partial lobectomy, and cystectomy was performed in five patients.

RESULTS

On magnetic resonance angiograms, nonvisualization or stenosis of the hepatic veins was detected in all cases. In one patient thrombosis and in another patient severe stenosis of the inferior vena cava were associated. The portal hilum was displaced anterosuperiorly in five patients. Intrahepatic collaterals were present in six patients and extrahepatic collaterals were seen in three. Associated thrombosis in the left portal vein was found in two patients.

CONCLUSION

We conclude that patients with complicated hydatid cysts and who have had postoperative complications should be checked not only for recurrence or abscess formation, but also for vascular changes. magnetic resonance angiography is a useful alternative imaging technique and can provide useful information at one session within several minutes in patients who had undergone surgery for hydatid cyst of the liver.

Liver transplantation: the last measure in the treatment of bile duct injuries

BACKGROUND

Bile duct injury (BDI) is a severe complication that may arise during the surgical treatment of a benign disease. A significant proportion of cases develop end-stage liver disease and a liver transplant is required. The aim of this study was to analyze the indications and results of liver transplantation as treatment for BDI.

METHODS

Between January 1988 and May 2007, 20 patients with end-stage liver disease secondary to BDI were included on the liver transplant waiting list. Retrospective charts were analyzed and survival was estimated by the Kaplan-Meier test.

RESULTS

Four patients died while on the waiting list and 16 received a transplant. Injury to the bile duct occurred during a cholecystectomy in 13 of 16 patients, with the main cause of the lesion being duct division in six patients and resection in four. All patients had received some surgical treatment (median = 2 procedures) before being considered for a transplant. The liver transplant came from a cadaveric donor for all patients and the median time between BDI and liver transplant was 60 months. Two patients died in the postoperative period and nine had complications. Three patients died in the late postoperative period. Median follow-up was 62 (range = 24-152) months. One-, three-, and five-year survival rates were 81, 75, and 75%, respectively.

CONCLUSION

Complex bile duct injuries and bile duct injuries with previous repair attempts can result in end-stage liver disease. In these cases, liver transplantation provides long-term survival.

Major hepatectomy for the treatment of complex bile duct injury

BACKGROUND

Postcholecystectomy complex bile duct injuries involving the hilar confluence, which are often associated with vascular injuries and liver atrophy, remain a considerable surgical challenge. The aim of this study is to report our experience of major hepatectomy with long-term outcome in these patients.

METHODS

From January 1987 to January 2002, 18 patients underwent a major hepatectomy for complex bile duct injuries. The hilar confluence was involved in all cases and was associated with vascular injuries in 13 (72%), including arterial injuries in 11, and partial liver atrophy in 15 (83%). The average time interval between the initial cholecystectomy and hepatectomy was 43 +/- 63 months and 16 (88%) patients had previously undergone an average of 2 (range 1-3) surgical repairs.

RESULTS

Major liver resection included a right hepatectomy in 14 (78%) patients, a left hepatectomy in 3, and a left trisectionectomy in one. There was no postoperative mortality, but severe postoperative morbidity was experienced in 11 (61%) patients, including biliary fistula in 7 (39%), prolonged ascites in 8 (44%) and hemorrhage requiring reoperation in one. With a median follow-up time of 8 years (range 3 to 12), 17 (94%) patients have excellent or good results, including 13 patients without symptoms.

CONCLUSION

This study shows that salvage major hepatectomy is an efficient treatment for patients with complex hilar bile duct injuries and should be considered before liver transplantation or recourse to metallic stents.

Complex bile duct injuries: management

Laparoscopic cholecystectomy is the present treatment of choice for patients with gallbladder stones, despite its being associated with a higher incidence of biliary injuries compared with the open procedure. Injuries occurring during the laparoscopic approach seem to be more complex. A complex biliary injury is a disease that is difficult to diagnose and treat. We considered complex injuries: 1) injuries that involve the confluence; 2) injuries in which repair attempts have failed; 3) any bile duct injury associated with a vascular injury; 4) or any biliary injury in association with portal hypertension or secondary biliary cirrhosis. The present review is an evaluation of our experience in the treatment of these complex biliary injuries and an analysis of the international literature on the management of patients.

Bile duct injury during cholecystectomy requiring delayed liver transplantation: a case report and literature review

Major bile duct injury during cholecystectomy represents potentially severe complications with unpredictable long-term results. If these lesions are not treated adequately, they can lead to hepatic failure or secondary biliary cirrhosis therefore requiring liver transplantation. We report a patient who required liver transplantation 15 years after open cholecystectomy. A l0-year old girl underwent open cholecystectomy and duodenal repair for cholelithiasis and cholecystoduodenal fistula. She required two surgical interventions, hepaticojejunostomy which was performed in another center and portoenterostomy for biliary stricture at our institution seven years after the cholecystectomy. Eight years after the third operation, she required recurrent hospitalization for treatment of hepatic abscesses. The extremely short intervals between the three life threatening episodes and the rapid progression to severe sepsis were taken into consideration and liver transplantation was performed at the age of 25. She is leading a healthy life at 4 years post transplantation. Although iatrogenic biliary injury can usually be treated successfully by a combination of surgery, radiological and endoscopic techniques, patients with severe injuries develop irreversible liver disease. This case report and review of the literature suggest that liver transplantation is a treatment modality for a selected group of patients with end-stage liver disease secondary to bile duct injury.

Sclerosing cholangitis secondary to hepatic artery ligation after abdominal trauma

Several causes have been postulated as responsible for secondary sclerosing cholangitis (SSC), mainly in adults, and, although in very different situations, ischaemia seems to be one of the most important factors. The term 'ischaemic cholangitis' has been used as a collective label for all these ischaemia-induced bile duct lesions. The biliary epithelium is dependent on arterial blood flow, unlike the hepatic parenchyma, which receives a dual blood supply from the hepatic artery and the portal vein. This makes the biliary epithelium very susceptible to changes in arterial blood flow. We present one adolescent patient who developed SSC after abdominal trauma with hepatectomy and ligation of the right hepatic artery. Different factors could have helped in the development of SSC in our patient (septicaemia, bile duct destruction, cholecystectomy) but right hepatic artery ligation seems to be the most important aetiological factor in the development of secondary ischaemic cholangitis.

Postoperative jaundice

Abnormal LCTs after surgery are common, and consultants are frequently called on to evaluate critically ill patients with abnormal tests. All patients undergoing consideration for elective surgery and a history of either acute or chronic liver disease require careful presurgical evaluation. A thorough history and physical examination, complete blood count, routine electrolytes, LCTs, and a coagulation profile should be ordered. For patients with marginal hepatic reserve, it is important that patient well-being be maximized before any elective operation. The type of surgery to be performed should also be reviewed. All patients with postoperative jaundice should be evaluated for a history of liver disease. The consultant should also review the surgical procedure performed, anesthetic agents administered, other medications used, and whether blood products were given during the perioperative and postoperative periods. The pattern and timing of LCT abnormalities may also give a clue to the underlying disorder. As in the preoperative assessment, a routine complete blood count,electrolyte panel, LCTs, and coagulation profile should be ordered. Unconjugated hyperbilirubinemia can develop as a consequence of blood transfusions, underlying hemolytic disorders, resorbing hematomas, drug effects, or Gilbert's syndrome. A haptoglobin, reticulocyte count, LDH, and Coomb's test should be considered in patients with unconjugated hyperbilirubinemia. Treatment is directed toward the underlying condition. Conjugated hyperbilirubinemia can occur as a result of either intrahepatic or extrahepatic disorders. Markedly abnormal aminotransferases and LDH in conjunction with a normal abdominal ultrasound scan suggest ischemic liver injury, drug-induced hepatitis, or viral infections of the liver. Treatment entails restoration of hepatic perfusion, removal of offending medications, and supportive care or antiviral agents, respectively. Extrahepatic biliary obstruction must be considered in all patients with conjugated hyperbilirubinemia. Abdominal sonography is the best screening test to assess for obstruction. Patients with common bile duct stones usually require ERCP with sphincterotomy and stone removal. Biliary strictures or leaks may require ERCP with balloon dilation of strictures or stent placement for strictures and leaks; percutaneous drainage of bilomas in combination with broad-spectrum antibiotic agents is recommended for patients with bile leaks and large intra-abdominal fluid collections. Surgery may be required for patients with strictures or leaks not amenable to either endoscopic or percutaneous intervention or for patients who have transected bile ducts after laparoscopic cholecystectomy. Medication effects, benign postoperative jaundice, sepsis, TPN, and acalculous cholecystitis are responsible for intrahepatic cholestasis and conjugated hyperbilirubinemia. Treatment includes removal of offending drugs, supportive care, broad-spectrum antibiotic agents with drainage of infected fluid collections, adjustment of TPN, and either cholecystectomy or cholecystostomy, respectively.

Right hemihepatectomy for bile duct injury following laparoscopic cholecystectomy

Laparoscopic cholecystectomy (LC) has become the treatment of choice for patients with symptomatic cholecystolithiasis. But with the introduction of this technique, the incidence of bile duct injuries has increased. We report the case of a 33-year-old man who was transferred from an affiliated hospital to our department for the treatment of a bile duct injury 2 weeks after LC. Prior to transfer, a laparotomy had been performed, with insertion of a T-tube and a Robinson drain on day 5 after LC. Endoscopic retrograde cholangiography (ERC) on admission day revealed an extensive defect of the right biliary system, which could not be treated endoscopically. An emergency laparotomy had to be performed at night for acute bleeding from the portal vein. Due to massive inflammation in the porta hepatis and intraparenchymal destruction of the right bile duct, liver resection was performed 2 days later, after the patient had stabilized in the intensive care unit (ICU). The patient had a prolonged postoperative course, but he finally recovered well from these operations. In conclusion, the management of bile duct injuries should include ultrasound to detect and drain fluid collections and ERC to classify the injury. Emergency laparotomy should never be performed without these examinations, since the majority of bile duct injuries can be treated endoscopically. Surgery for this serious complication should always be performed at specialized centers for hepatobiliary surgery.

Progressive sclerosing cholangitis after septic shock: a new variant of vanishing bile duct disorders

BACKGROUND

We present nine patients with progressive sclerosing cholangitis after septic shock.

PATIENTS

All nine patients had previously required long term treatment in an intensive care unit for septic shock: two patients with polytrauma, five with burn injury, and two with extensive surgery. They were admitted to our hospital because of cholangitis. Endoscopic retrograde cholangiography revealed severe intrahepatic stenoses in all patients and liver biopsies showed typical signs of sclerosing cholangitis. No patient had pre-existing liver disease.

RESULTS

Mean follow up time was 35 months. In patients with major bile duct stenoses (3/9), 12 endoscopic dilations were performed in total. In one patient, concrements were extracted and intermittent stenting was necessary. To date, 4/9 patients have rapidly developed liver cirrhosis. During follow up, 5/9 patients died: two after fulminant cholangitis, one after liver failure, one due to liver transplantation associated problems, and one after cerebral ischaemia. One patient has been registered for transplantation and the remaining three patients show no acute signs of liver failure.

CONCLUSIONS

Patients with sclerosing cholangitis, following septic shock, represent a new variant of vanishing bile duct disorders. In such patients liver disease rapidly progresses to cirrhosis. Endoscopic treatment may only transiently improve the course of the disease. Orthotopic liver transplantation is indicated in end stage disease.
